Before you go to court, you will both complete a big form (Form E) where you have to give details of all your assets and liabilities, the value of any property (houses, cars, expensive jewellery) pensions, earnings, expenditure etc. If his form raises questions, e.g, 'where did that £1000 come into his account from?' or 'what about that pension he was paying into and hasn't disclosed?' your solicitor will put together a list of questions and send it to him just before the first hearing.
The court bit is a 3-stage process:
First Appointment: the court makes directions to make sure you and the judge have all the information you need. This could include getting the house valued, setting a date to reply to each other's questionnaires, evidence of your mortgage capacities and properties that would be suitable for you and him, if you're going to need a new house. The two solicitors will talk to each other at court and will probably be able to agree what directions are needed. The judge will most likely have you in for a couple of minutes and sign it off.
Financial Dispute Resolution: Negotiation Day. Take plenty of change for the car park and a packed lunch. You could be there all day. With the judge's help, you will do your very best to negotiate a settlement via your solicitors. The judge will read all the papers and your solicitors will explain the issues, and the judge will give an indication of the sort of settlement he or she thinks is about right. Most people manage to agree at this point, but if you can't, directions will be made for a...
Final Hearing: you'll probably file witness statements in advance, and there will be directions for anything else the court needs, and you'll update your financial disclosure. With the help of the solicitors you can have one more go at negotiating, but if that doesn't work, the judge will hear evidence from you both and make a decision.
The judge is looking at how to stretch the assets to meet both of your needs, giving priority to any children's needs. The law is s.25 Matrimonial Causes Act 1973 which is in reasonably plain language if you google it. Sob stories don't get very far unless they're relevant - e.g. a bad foot is only of interest if your job requires standing up all day and you just can't do it any more and have medical evidence to confirm it.
